SSD solutions restructuring are charges related to the restructuring of our underperforming Shannon and Bigtera product lines and include goodwill and intangible assets impairment expenses, the write-down of NAND flash and SSD inventory valuation and customer sales returns and accounts receivable attributable to these product lines.

Amortization of intangibles assets consists of non-cash charges that can be impacted by the timing and magnitude of our acquisitions. The Company considers its operating results without these charges when evaluating its ongoing performance and forecasting its earnings trends, and therefore excludes such charges when presenting non-GAAP financial measures. The Company believes that the assessment of its operations excluding these costs is relevant to its assessment of internal operations and comparisons to the performance of its competitors.

Litigation expenses consist of legal expenses relating to intellectual property disputes, commercial claims and other types of litigation. While litigation may arise in the ordinary course of our business, we nevertheless consider litigation to be an unusual and unplanned activity and therefore exclude this charge when presenting non-GAAP financial measures.

Foreign exchange gains and losses consist of translation gains and/or losses of non-US$ denominated current assets and current liabilities, as well as certain other balance sheet items which result from the appreciation or depreciation of non-US$ currencies against the US$. We do not use financial instruments to manage the impact on our operations from changes in foreign exchange rates, and because our operations are subject to fluctuations in foreign exchange rates, we therefore exclude foreign exchange gains and losses when presenting non-GAAP financial measures.

Gain on disposal of long-term investments relate to gains from our sale of FCI, our specialty RF IC product line, and the sale of our investment in ProGrade, a professional-grade memory card manufacturer.
